I've several large files stored in U1. When I move a file to another folder (which is also synced) it triggers a re-upload of the file. The same happens if I copy the file to another folder. Doesn't U1 use the hash to identify similar files and save bandwith?

Using U1 on Lucid.

This has been fixed in the version shipped in Natty. If you don't want to upgrade, you can use a cutting edge version of Ubuntu One by using the nighly PPA, although it does come with some risk of it breaking from time to time:

I think I remember that I've read somewhere that improvements to U1 will be made available to all Ubuntu versions. Using the unstable nightlies is not really a sulution. I hope U1 will be updated more frequently on all active releases. I mean, if an U1 client proofs stable for several month on a new release it could be released for LTS users as well. I think that especially U1 evolves fast and improvements should be available to all Ubuntu users. U1 competes with other solutions like Dropbox & SpiderOak. – Andre Jun 1 '11 at 9:41
